DOUBLE STAMP-HAMMER.

SPECIFICATION forming part of- Letters Patent No. 651,754, dated June 12, 1900.

Application filed December 15 1899, Serial No. 740,430. (No model.)

To all whom it may-concern:

Be it known that I, HENRI GUYoT, a citizen of the Republic of France, residing at La Souterraine, department of Oreuse, France, have invented new and useful Improvements in Double Stamp-Hammers, of which the following is a specification.

My invention relates to double stamp-hammers formed of a base a, the upper surface of which is provided with two grooves b for receiving steel blocks serving as anvils. The base a supports a horseshoe-shaped armature c, which supports the upper part of the machine. 1

In the accompanying drawings, Figure 1 is a front elevational View of my construction. Fig. 2 is a side view thereof, showing the armature which supports the upper structure. Figs. 3, 4, and 5 are views of details of my construction, showing more particularly how the two eccentrics are simultaneously operated by one pulley. I

The upper part of my construction comprises two uprights d and d, which at their tops form two arms, so as to embrace three pulleys, of which the two lateral, e and e, are fixed pulleys, while the central pulley f is loose. Each of the fixed pulleys has for its object to operate an eccentric g or g, or, by means of a peculiar system of keying, one of these fixed pulleys can be made to operate simultaneously the two eccentrics. This arrangement will be described hereinafter. A rod h h is linked, respectively, to each of the eccentrics g g. These rods can be regulated as to their length, and their ends are each provided with a spring in order to indesired direction by means of a lever 19, os-

cillating at the point 1), Fig. 1, operated by hand by means of a rod g and a lever g.

The displacement of the belt-shifting fork r is effected by means of a sliding rod 4", actuated from right to left, and vice versa, by means of an elbowed lever s, a rod 8', and a lever 25.

Considering the belt arrangement for engaging and disengaging the same, it will be possible to make either of the pulleys turn at will, and thus to bring into action either of the hammers, and by means of the key n it will be possible to have both hammers operating simultaneously, no matter upon which of the fixed pulleys the belt be placed.

Having now described my invention, what I claim is- 1. The combination with two hammers, of a standard common to both, two operating crank-shafts, one for each hammer, said shafts being in line with each other, a source of power adjacent to both shafts, and means for con necting it with either one of said shafts at will.

2. The combination with two hammers, of a standard common to both, two operating crank-shafts, one for each hammer, said shafts being in line with each other, a fixed crease the force or the fall of the corresponding hammers v1 or e". The hammers 1 t" are guided by triangular guide-rods j, fixed to the uprights d d and to two uprights d d", fixed to the former by cross-beams k. Said hammers it" are located in the same vertical plane as the grooves b of the base a, in which the anvils are received, as above stated.

The peculiar mechanism for actuating simultaneously the two eccentrics by one pul- .ley only works as follows, Figs. 3, 4, and 5:

The driving-shaft which carries the pulleys is made of two parts, one solid Z and one hollow part Z, into which the solid part fits.

pulley on each shaft, a loose pulley between said fixed pulleys, and means for shifting a belt from said loose pulley to either one of the fixed pulleys at will.

3. The combination with two hammers, of a standard common to both, two operating crank-shafts, one for each hammer, said shafts being in line with each other, means for rotating one of said shafts, and means for locking said shafts together as one.

4. The combination with two hammers, of a standard common to both, two operating crank-shafts therefor arranged in line with each other, means for rotating one of said tached to said key, an elbow-lever engaging said colla'igand means for operating said lever.

In testimony'that I claim the foregoing I have hereunto set my hand this 15th day of November, 1899.

HENRI GUYOT.
